The piede' i3, as showin, is coveied in e suiiebie cese, and located adjacent e miiway'iieck. Seid piede is adjiislszdiie Verisicaiij and carried iii the guide immes M, mounted oii the iiee L5, and is 'provided with e rack i6 on cec-ii oi is vei'iicel edges adaptiiidied to project through slots in the frames 14 14" to engage the pinion wheels by which it is raised. Said pinion wheels are oppositely rotated by the electric motor A which is energized by an electrical circuit leading thereinto, and controlled lov the action oi' the operating mechanism of the semaphore signal hereinafter described, and the operation is communicated to the pinions through a series of intermediate gears and Wheels as follows: The drive pinion 17 on the motor armature meshes with the large gear 18 mounted on the motorhon, which meshes with the driven gear 19 mounted on vertically adjustable hearings 2G carried on the hase l5 or the tripping plate frame. @n the opposite end ot the shaft 21 on which the gear 19 is carried is rigidly mounted the gear Wheel :'22 which meshes with the gear Wheel 28 of equal size therewith, and mounted on the shaiit 24, and said gear 23 meshes with gea-r 23 of similar size moirted on shaft 23". Rigidly mounted on the shafts 2l and 2d are the sprocket wheels 25 and :26 respectively which actuate the chains 27 and 2S respectively and which pass over the sproclret wheels 29 and 30 mounted on the same shafts on which are rigidly carried the pinions 3i and 312 and by which said pinions are operated in opposite directions to raise the tripping plate 13.

rihe electric circuit by which the'motor i is energized, :doive through a circuit breaker C mounted on the trame le, which is normally closed, hut the `tripping plate i5 is provided 'th a lug B so positioned that it will en gage the circuit breaker C and disengage the contacting `laces thus stopping the action ci the motor. ihe tripping plate, however, is neld uin raised. position by' the spring aetnated latch E which engages a keeper E just prior to the breaking o" cncuit and the completion of the raising of the plate. Said latch is connected with an armathre l? adapted to he actuated by magnet G which is energized hy a circuit is controlled by the adjustment or the semaphore signal operating mechanism to safety position, 1which thereby releases the latch and permits the tripping plate to drop hy gravity ont ci' the path or the trigger l2.

lt will be apparent from the oregoing description, and as illustrated lig. 9 of the drawings, that the operation of my device is accomplished by two electrical circuits, which are supplied by the line wires H and i leading from any suitable source or supply. Both circuits are primarily controlled by the Contact plate 33 carried on the operating arm 34 ot the semaphore. When said arm is positioned at danger, as shown in dotted lines, it contacts the plate 33 with the contact points 35 and 36, which completes the circuit through Wires 37 and 38 and the circuit breaker C to the motor A. Upon the completion of the upward travel of the tripping plate, the circuit breaker C is disconnected to stop the operation and the waste of electricity.

When the arm is raised to safety, as shown in full lines in Fig. ,9, the motor A energia` ing circuit is broken, and as said arm travels upward the plate 33 contacts for a brief period with the points 39 and 40 of the Wires 39 and 40 which energizes the electromagnets G to release the latch and permit the plate i3 to drop, after which, on the completion of the travel of the arm, said circuit is broken by the dis-connecting of the contact 39 from the plate 33.

lt will he understood that the semaphore mechanism is operated by an electric circuit controlled by the approach and departure orl1 a locomotive or train Within the adjacent hlochs.

in operation, the cap and trigger l2 are placed on the nipple 8 to close the end of the fixture carried on the air-brake system on the locomotive as shown in Figs. l, 6 and 'Il' of the drawings. if the semaphore signal is set at saiety the tripping plate 13 is depressed and the trigger will pass over same, but if the semaphore is positioned at danger, the electro-motor A is energized by the electric-circuits hereinbetore described, and the tripping plate is elevated to such position that should the approaching train attempt to pass the danger signal, the plate will en vage the trigger and turn it and the cap surnciently tol register the notches and lugs on the cap and nipple, whereupon the spring S forces the cap od and admits air to the-brake pipes and sets the bra-hes to bring the train to a stop.

Having thus described my invention, l claim as new, and desire to be secured hy 'etters Patent, is

l. ln a train stopping device, the combination with a semaphore signal mechanism having an oscillating arm and electric contacts thereon, of a vertically adjustabie track obstacle, an electric motor geared with said obstacle for raising same, a latch for holding said obstacle in raised position, :1n-electro-magnet or releasing said latch, an electric circuit connected with the contacts on the semaphore arm when in lowered position for actuating the motor to raise the obstacle, and an electric circuit connected with the contacts on said semaphore arm when in raised position to actuate said latch-operating electro-magnet to permit said obstacle to lower,.substantially as described. v
